Code Issues Proposed changes

Add whitelist and blacklist file options to tempest run

Browse Source 
This commit uses the regex_builder logic from os-testr to construct a
regex given a whitelist and/or a blacklist file. Where all matches from
the blacklist file will be excluded and all matches from the whitelist file
will be included.

Partially-Implements bp tempest-run-cmd

@ -23,6 +23,27 @@ Tempest run has several options:
any tests that match on re.match() with the regex
* **--smoke**: Run all the tests tagged as smoke
There are also the **--blacklist_file** and **--whitelist_file** options that
let you pass a filepath to tempest run with the file format being a line
seperated regex, with '#' used to signify the start of a comment on a line.
For example::
# Regex file
^regex1 # Match these tests
.*regex2 # Match those tests
The blacklist file will be used to construct a negative lookahead regex and
the whitelist file will simply OR all the regexes in the file. The whitelist
and blacklist file options are mutually exclusive so you can't use them
together. However, you can combine either with a normal regex or the *--smoke*
flag. When used with a blacklist file the generated regex will be combined to
something like::
^((?!black_regex1|black_regex2).)*$cli_regex1
When combined with a whitelist file all the regexes from the file and the CLI
regexes will be ORed.
You can also use the **--list-tests** option in conjunction with selection
arguments to list which tests will be run.
